| 摘 要： | 通过大田试验,在饼肥和无机肥合理配施的基础上,增施不同的有机酸,研究其对烤烟生长发育及品质的影响。结果表明,腐殖酸、柠檬酸和油酸能明显促进烟株地上部的生长及根系的发育;腐殖酸和柠檬酸能提高烟叶中的矿质营养成分含量,提钾降氯,明显改善烟叶品质并提高烤烟产量和中上等烟比例;熟芝麻和油酸能显著提高烟叶中有机营养成分。因此,在无机肥与饼肥合理配施的基础上,熟芝麻、脂肪酸等在促进根系发育,提高N、P、K在烟叶中的积累量和分配比例,提高烤烟产量和上中等烟比例,改善品质等方面有不同的效果。

| Abstract: | The effect of different organic nutrition on growth, development and quality of flue-cured tobacco was investigated. The results show that combined application of organic -chemical fertilizers, humus acids and lemony acids can remarkably improve mineral nutrients, raise the yield and improve the quality of tobacco leaves. Oleic acid can promote the growth of root. Sesame and oleic acid can clearly improve organic nutrients in tobacco leaves. |
